Abstract: Nano-metal-matrix composites (NMCs) are novel composite materials in which nano-phase such as nanoparticles, nano-rods, nano-structured materials are reinforced with metals or alloys to improve the physical, mechanical, wear and other properties.In the present study, Al6061 alloy has been chosen and used as the matrix material and nanoclay as the reinforcement. Composites were prepared by using liquid metallurgical rout (stir casting method) nanoclay particle content was increased from 0 to 20 % in steps of 5% by weight Corrosive erosive wear test was conducted on Al-Nanoclay metal matrix by corrosive-erosive wear tester. Three specimens are tested at a time for constant conditions as per ASTM standards, the matrix material without the reinforcements was also subjected to the wear tests to achieve a comparing with the composite material with different percentages of nanoclay. From the results it is observed that, Corrosive erosive wear rate varies marginally at lower speeds but increase sharply at higher speed. The corrosive wear rate logarithmically increased with the increasing concentration of the corrosive medium. The composites attained better corrosive-erosive (Vce) wear resistance than the matrix alloy irrespective of the test condition The erosive-corrosive wear rate of the specimen have an exponential relation with the HCL concentration and erosion speed of the slurry, Corrosive wear was the predominant mechanism of material removal in the corrosion and abrasion modes of wear. The effect of abrasive particles and corrosion medium on the wear behaviour of the composite is explained experimentally and compared with ascast aluminium alloy
